Open the CIPO recordAbstract From the Canadian patent
The present invention discloses steroid/thyroid hormone receptor DNA binding domain compositions that determine target gene specificity. The invention further discloses methods converting the target gene specificity of one receptor into the target gene specificity of another. Still further the invention discloses novel assays for identifying ligands for orphan. hormone receptors. These assays are especially useful since they avoid the necessity of constructing chimeric genes and proteins in order to search for ligands that can activate a putative receptor.

Why it's free to use
- Filed March 16, 1990 and granted July 10, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 16, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 16, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
